LINING OF METALLURGICAL VESSEL BATH Russian patent published in 2006 - IPC F27D1/00 F27B3/14 

FIELD: non-ferrous metallurgy, namely linings of metallurgical aggregates for melting and casting aluminum and its alloys.

SUBSTANCE: lining of metallurgical vessel bath for melt aluminum or its alloys includes metallic casing, heat insulation and fire resistant lining being in contact with melt metal. In order to create protective layer of hard metal in layer of heat insulation lining along interface with fire resistant lining, heat insulation lining has thickness consisting 0.35 - 0.55 of thickness of fire resistant lining. Said layer of hard metal is formed due to crystallization of melt metal penetrated in lining at operation. Metallic casing is provided in addition with screen mounted with gap relative to outer surface of casing and forming together with casing walls open ducts for air circulation. Casing may have cooling ribs secured to its outer surface.

EFFECT: lowered heat losses at operation, improved strength of lining.
